White paper towels for a substrate are recommended for all newly-acquired snakes while quarantined (or for the first month+ if the only snake) so that issues show up easily & can be addressed. Things like mites or any bleeding from the cloaca, for example, are things you'd want to be immediately aware of, since mites can kill snakes (small or stressed ones even more quickly) & blood might be from a prolapse or a gastrointestinal issue. (No need for a new thread...It's all related to your new set-up.)
